Mary Anne and Me: Officially Cheating

Have you cheated on your spouse? Not just long showers thinking of your hot neighbor or watching porn ready to click Alt+tab or Alt+F4. I mean humping someone, not the paid ones. It didn’t just happen. Little seductions grew to where your best friend, the person whom you consider a sister is in bed with you. And you do all sorts of nasty things reserved for your wife. Yes, I’ve cheated on my wife.
Mary Anne is a close friend of my wife and I. Her husband is likewise our friend. But we flirt and talk dirty. But we just pass it off as mere jokes between friends. Little did I know Mary Anne also thinks about me in inappropriate ways. We let our urges take control and we find ourselves in an adulterous situation. As immoral as it may sound, I enjoy cheating with my friend a lot.
